NAIROBI, Kenya (AP) - An aid agency says Ugandan rebels have killed more than 400 people in northeastern Congo since Christmas Day.
The agency, Caritas, cited reports by its staff in the region.
In a statement on its Web site Tuesday, the group says: "Caritas is shocked by its staff reports of a series of massacres in the Democratic Republic of Congo carried out by Ugandan rebels on Christmas Day and the days following."
The statement did not cite evidence that Uganda's Lord's Resistance Army rebels had carried out the attacks. The rebels and the Ugandan government have accused each other of being behind recent attacks in the remote area - with both denying responsibility.
The army and the rebels did not return telephone calls Tuesday.
